Question 1

How to troubleshoot MMWormhole messages not being received?

Accepted Answer

Check that App Groups are correctly configured in Project Capabilities, as shown in the README's troubleshooting images. Ensure both app and extension are signed with the same team and have the App Group enabled, and verify directory names match during initialization.

Question 2

MMWormhole or Apple's WatchConnectivity: which should I use for watchOS?

Accepted Answer

MMWormhole builds on WatchConnectivity for simplicity with its session transiting types, but for advanced, direct control over watchOS communication, native WatchConnectivity might be better. Use MMWormhole for quick setup with basic message passing between iOS and watchOS.

Question 3

Can MMWormhole handle passing images or large files?

Accepted Answer

Yes, since it uses NSCoding-compliant objects archived to files, but large data can impact performance due to file I/O. It's best suited for small, frequent messages like strings or JSON, as mentioned in the overview about simple sharing.

Question 4

How do I set up App Groups for MMWormhole in Xcode?

Accepted Answer

Go to Project->Capabilities->App Groups, enable it, and add a unique identifier. Both the app and extension must use the same group, as detailed in the Getting Started section, and ensure three checkmarks are displayed in the steps.

Question 5

What's the difference between file transiting and session transiting in MMWormhole?

Accepted Answer

File transiting uses shared directory archives for persistence, while session transiting leverages WatchConnectivity's application context or messages for real-time communication with watchOS. Choose based on whether you need background compatibility or low-latency updates.

Question 6

Is MMWormhole suitable for real-time multiplayer games?

Accepted Answer

Not ideal, as it relies on file I/O and background modes, which can introduce latency. For real-time gaming, consider lower-latency IPC methods or network-based solutions, since MMWormhole is designed for basic extension communication.

Question 7

How to implement a custom transiting protocol in MMWormhole?

Accepted Answer

Create a class conforming to MMWormholeTransiting protocol, overriding methods for reading and writing messages. Then initialize MMWormhole with this custom transiting type using the optional initializer, as described in the message transiting options section.
